Question

For the whole number $1729,$ predecessor is and successor is .

Answer 1

$\underset{–}{\text{Precedessor of a Whole Number}}:$

• A predecessor is a whole number that comes right before/immediate before/just before a given whole number on a number line.
• Suppose a whole number is $\ast$, then the predecessor of $\ast$ is a whole number that comes just before $\ast$ on the number line, i.e., $(\ast -1)$.
• Thus, to find the predecessor of any whole number, we have to move $1$ unit just before the given whole number.

Now, let's represent $1729$ and it's predecessor on a number line.


$\therefore \text{Predecessor of}1729\text{is}\underset{–}{1728}.$

$\underset{–}{\text{Successor of a Whole Number}}:$

• A successor is a whole number that comes right after/immediate after/just after a given whole number on a number line.
• Suppose a whole number is $\ast$, then the successor of $\ast$ is a whole number that comes just after $\ast$ on the number line, i.e., ($\ast +1$) .
• Thus, to find the successor of any whole number, we have to move $1$ unit just after the given whole number.

Now, let's represent $1729$ and it's successor on a number line.


$\therefore \text{Successor of}1729\text{is}\underset{–}{1730}.$
